Kua tāruatia ki te papatopenga
80x+1100-110x<1000
Whakamahia te āhuatanga tohatoha hei whakarea te 110 ki te 10-x.
-30x+1100<1000
Pahekotia te 80x me -110x, ka -30x.
-30x<1000-1100
Tangohia te 1100 mai i ngā taha e rua.
-30x<-100
Tangohia te 1100 i te 1000, ka -100.
x>\frac{-100}{-30}
Whakawehea ngā taha e rua ki te -30. I te mea he tōraro a -30, ka huri te ahunga koreōrite.
x>\frac{10}{3}
Whakahekea te hautanga \frac{-100}{-30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -10.
